However, Digital heritage; for instance by some people means the field that utilizes digital media in the services of cultural heritage, may be through some certain simplification. Sometimes it is also considers as 3-dimensional virtual environment for navigation and roaming around. Again it also considers as any digital-representations of heritage, including text‐based forums, images and websites. So the domain of digital heritage lies at the “intersection between cultural heritage and digital media” (Parry, 2007, p xii). From the point of Museology, Ross Parry (2007) referred digital heritage as ‘e-tangibles’. UNESCO’s programme aiming at preservation and dissemination of valuable archive holdings and library collections worldwide has been mentioned as ‘E-Heritage’ (source: http://portal.unesco.org/ci/en/ev.php-URL_ID=24268&URL_DO=DO_TOPIC&URL_SECTION=201.html, dated 02.04.2010).
However, according to the UNESCO’s Charter for the Preservation of Digital Heritage (2003), ‘digital heritage’ has been defined as “unique resources of human knowledge and expression. It embraces cultural, educational, scientific and administrative resources as well as technical, legal, medical and other kinds of information created digitally or converted into digital form existing analogue resources”. So the field of digital heritage is still wide and comprises any media based on digital technology. Any form of digital content either 2D (e.g. text, image, motion pictures) or 3D (e.g. virtual environment, 3D object) both falls under digital heritage. For example – a digital sound recording of a local oral history, a high resolution scanned image of a painting, a digital video recording of a ritual, a piece of multimedia art (DVD), a curators note in HTML about an object, a 360-degree virtual model of a real or imaginary space, a personal blog explain the past history, a digital photograph submitted by a local visitor to a museum’s community history project – all falls under ‘digital heritage’.
 UNESCO adopted the Charter on the Preservation on the Digital Heritage in 17th October 2003. The Charter recognises the significance and value of born digital resources and calls for member states to co-ordinate their efforts in this.
